    using blockchains to track the movement of goods, like from ports or for cheese, is probably their only non-BS use case other than volatile currencies

    We already do this with barcodes and QR codes, which you can just make with a printer.

      No? Barcodes and QR codes do not have enough information for unique identification. (Well they could but they start getting bigger and bigger)

      But the real issue is needing these codes tracked and audited in a public manner. Instead of having a third party company trusted with all the cheese, you use a Blockchain with a public ledger. This doesn’t even require much processing power since there’s no incentive to mine as many blocks as possible.

      I hate cryptobros but logistics is a good use for the tech. Tech is tech, not all use cases are bad.

      QR codes are just symbols in a camera readible way and barcodes numbers in a camara readible way.
      A storage medium for 0´s & 1´s like a USB stick or a disc but way less storage.

      They dont add any security, heck when you would have looked at barcodes you would likely have realised that the same product uses the same code (and not each one being unique)

      Their use cases are cashiers dont have to manually find/type each product into their terminal but have a scanable ID & QR Codes are mostly to open websites as users without having to type a potentionally long URL.
      In booth cases they remove the human error.
